Softening Agent

Softening agents improve the flexibility, suppleness and elasticity of the plastic and ensure that it is easy to process. Furthermore, they improve the behavior of the material during temperature fluctuations. The softening agent molecule squeezes itself between the molecule chains, which become easier to move as a result. The plastic becomes more supple.

The quality of the softening agent and its proper combination has a considerable influence on the quality of the film.

Monomer and polymer softening agents in particular are referred to here in. Monomers are chemical components, therefore they are links from which a molecule chain is constructed. When the molecule chain is comprised of more than 100 monomer components, they are referred to as macromolecules and/or Polymers.

Solid Ink Strictly speaking, solid ink is not ink but wax rods. The advantage of this is that it can be printed on virtually any material, without requiring a special coating. A disadvantage of solid ink is that the wax remains sensitive to heat. High temperatures due to sunlight or during lamination can cause the color to melt on the print material.
Solvents Solvents are components that appear in the form of mixtures particularly in colors and varnishes. In general, solvents are fluids which dissolve other materials without altering their chemical structure. The most common solvent is water. For inks, mainly organic compounds such as alcohol, petroleum or hydrocarbon are used. Different solvents can be more or less harmful to the environment which is why many manufacturers are now also producing mild-solvent / eco solvent inks. These contain only a small portion of the amount of solvent used previously.
Splices For production reasons, errors can occur on the surface of the film during manufacturing. In past years, many manufacturers chose to cut out these damages and the end product was two pieces of film "stuck together" The transition point between two pieces of film is called 'splice'. These methods were applied frequently in colored plotter films. In today's digital printing media, splices can no longer be used, as they could possibly cause damage to printer heads.
Storage Conditions The rolls should always be stored upright using the roll stand provided or be stored hanging. Roll stands that are free standing or that hang on the wall have proven to provide successful storage.
Surface Cleaners Surface cleaners are used to best prepare the surfaces to be bonded for the bonding with film. Grease, oil, protein and insect residue is removed from the surface, thus enabling optimal adhesion of the film to the background.
Surface Energy

The bonding behavior of the adhesives to the background varies with the surface energy of the adhesive as well as with the bonding behavior of the adhesive. In this respect, the electrical polarity of the adhesive to the background it is to be bonded to is important. So polar and apolar surfaces are recognized. There are also surfaces on which even good adhesives fail. The reason: the low surface energy repels the adhesive. In this instance one also refers to low energy surfaces. Examples of materials with low surface energy are polyethylene or polypropylene. In contrast, varnish, metals such as lead and brass, polycarbonate or acrylic glass demonstrate high surface energy.

Only high quality adhesives which match the respective requirements are suitable in order to avoid adhesion problems. Therefore, it is important to know prior to adhesion, to which background the film is to be bonded and that the background is clean and grease-free.

Thermal Inkjet Esta técnica de impresión trabaja con "burbujas" calientes y por ello también se denomina bubble jet. La tinta se calienta de golpe a 400°C, lo que hace que se transforme en gas y, con ello, se lance con mayor velocidad de la cámara de calefacción. Después, la cámara de calefacción se ha de enfriar y llenar de nuevo con color. Estos procedimientos tienen lugar en fracciones de segundo.
Translucence Translucence is the term used to describe the light permeability of materials. Films for backlit signboards are generally translucent to reveal color effects. In contrast, opaque films in backlighting weaken the brightness of the light.
Ultimate Adhesion

The adhesion of high-performance films does not happen immediately after bonding but develops over a longer period of time. This is normally over 72 hours. After this time, the maximum adhesive strength of the film is reached and this strength remains constant over the period of application. Vehicles should only be cleaned after this time, i.e. once adhesion has reached its full strength, to prevent premature peeling of the film.

UV Inks Basic components of UV inks are monomers and oligomers and photo initiators. irradiation with special UV lamps through the photo initiators, polymerization is initiated within the ink, so that the freshly printed layer rapidly forms a hard surface. UV inks as well as the necessary cleaning products require a so-called UV configuration of the printing press.
UV Printing UV printing technology uses a printing press with UV drying and offers the possibility to print on, for example, polyester, PVC or other closed surfaces. For UV printing, special UV-curing inks are used which, in contrast to conventional inks, contain no solvents
UV Stabilizers UV stabilizers protect the color pigments and the adhesive from yellowing. This is particularly important for transparent films (even protective laminate) or for processing films destined for long-term use.
